As the world tackles the coronavirus outbreak, HEPA filters have been touted as way to reduce the impact of similar viruses in the future.

The efficiency of HEPA filters is measured at MPPS (most penetrating particle size) that means this is the lowest efficiency of the filter. For smaller or larger particles that filter will perform even better.

MPPS is typically between 0,1-0,25 micrometer in size. Bacteria and viruses are often smaller than that but typically attach themselves to larger particles. It’s also important to understand HEPA filters do not actively kill living organisms. They capture and hold them within the matrix of the filter.

High efficiency air filters can be installed in HVAC systems, filtering out biological pollutants and particulate matter carried by the air-stream, preventing them from entering or recirculating back into the room.

As unfiltered air flows through the HVAC unit’s duct-work, the air filter captures and holds the airborne pollutants.

Camfil says that for further risk mitigation of airborne pathogens, it is recommended to upgrade or install the highest possible efficiency HEPA filtration (H13 or higher) in the existing ventilation system.
